Looks like a broken screen only on damaged screens. Go to factory ask for replacement

Yeah I think there may be a correlation between the screen and the Sim card / the antenna. (Not really an expert).
And I agree with DavidxxxD, because I can say for sure this is very uncommon, and the manufacturer will surely replace it as it isn't unusable.

Dear all,
I have a Legend with S-ON (1.01), and I used fake-flash to change ROMs. The mobile phone has been fine with a custom ROM for more than 3 months now.
Suddenly, 3 days ago, the phone rebooted while browsing settings and when it came back on, the device could not recognize the SIM card or connect to the network and get a signal.
The problem is weird because the device (a) can find networks if I search for them, (b) can make emergency calls, (c) connects normally to both wi-fi and the SIM 3G internet but does not:
- get signal (always zero lines)
- recognize the sim card (always asks me to rescan for new contacts, and the process fails)
I tried wiping everything, I tried reflashing, I tried flashing another ROM. The problem persists.
Would flashing a new RADIO potentially help? It is the only thing I have not tried.
I am really at a loss here. The device did not fall down, or had a knock or any other user damage. The problem started suddenly and i can'f find a way out of it.
Anyone who manages to find me a solution gets a paypal beer
PS: Something important is that the phone DOES know that SIM card is there, and DOES partially recognize it: I am asked to put my SIM card PIN, which is accepted correctly.
Hey
What I'd do:
1.)Try the SIM in another device - could be a SIM problem...
2.) As you are 1.01, there is no risk in Warranty repair, so unroot and send back to shop if the sim proves OK in another device..
Probably a stupid suggestion but i had at one point no service when my battery cover was not on...
When i was rooting mine, i kept the battery cover off because i was stuck so many times in the middle of running step 1... so never bothered putting the battery cover on...
after i succeeded in rooting, i still saw no service... but as soon as i put the battery cover on , i was able to pick up the network
@QkSi1ver: The Legend's antenna is located in the battery cover, which is why you would have had no reception with it removed.

Which could be the reason for the SIM problems : if it is not set correctly it can't communicate proper with the mobile , that's why it asks for searching for contacts ( I had a similar problem a few months ago )
no network signal!

i don´t believe it! first of all, thank u kindly for ending my nightmarish odyssey through expert forums across the globe!
that just did the trick, uber cool! and yet it sucks, because i wasted most of my sunday and half of today to solve this, wondering why nobody even mentioned connection probs.
maan, i´m tired, i´m going to bed!
My sim reader appears to be dead. The other day I go to use my phone and it says no signal, restart it and im good, browsing the web when all the sudden i get a message about no sim, insert sim and restart phone. So i restart and it was good for a couple days. Today my phone will not read a sim card. Tried my girlfriends captivate sim and no dice and my sim worked just fine in her phone. I odin back to stock to see if it would help but no dice. Seems like it must be hardware to me, has anybody had a similar problem.

Sounds like a bad solder joint or something hardware, unfortunately.
Hardware defects are covered by the warranty, should be able to get it replaced with relatively little hassle.... i say relatively, cause any time you're dealing with a warranty department There is inherently some hassle.
About a week ago when I tried to use my phone it said no SIM card inserted. The SIM was in and unlocked as I had used the phone about an hour before without any problem. I rebooted the phone but still it said no SIM so I powered off, removed the SIM, cleaned it and tried again. Well after about an hour of messing around the phone started working normally again. I didn't do anything more about it and wrote it off as a glitch.
I woke up this morning looked at my phone at it was asking for my PUK unlock code. It seems as though the phone must have rebooted overnight or something and now it's asking for a PUK. Why would it do that? I can't unlock it as my copy of the PUK code has worn so I cannot see all the numbers any more so I'll have to go to my network provider.
My question what could be wrong with the phone that is starting to not recognise the SIM? The issue last week must have been a prelude to this and it's pointing to something failing in the hardware. Any ideas what can be causing this?
Did you flash any ROMs or Kernels? Because that may be the problem usually.

Please give more informationhone Model,Kernel,ROM...
Sorry should have given more information about the phone.
It's a UK GT-I9100 model running stock 2.3.4. I haven't flashed any Roms since updating to 2.3.4 over a year ago. I've been holding out for the UK Jellybean which I've just downloaded ready to go once I sort out this problem.
I think I read somewhere that moisture on the usb port may cause this problem but I can't find that any more and I'm not sure if I'm remembering it correctly either. Although, my phone has never been submerged or even got wet in the rain so I don't think it's moisture.
I just tried putting another SIM into the phone and it works fine. As soon as I put my SIM back in it asks for the PUK. I guess I'll need to go speak to my network provider. Would still like to know why I started having these SIM problems.

Dude,I think your SIM card got blocked.Go to your carrer provider,and ask them to unblock it
I went to my network provider and got the PUK and unlocked the SIM. I asked if they had blocked it or if had been blocked and they said no. They said I must have entered the SIM pin incorrectly which isn't the case as the phone was one and the SIM unlocked before I went to sleep. I put it into flight mode and the next morning when I looked at the phone it was asking for the PUK. That with the previous issue where the SIM wasn't being recognised points to something not quite right either with the hardware or software.
I'm going to be updating to 4.2.1 no that the UK version is available and see if the problems still continue.
Ok u flashed a rom and have No SIM inserted or no service or that kind of error.I found this fix trying out things for myself.Take out your SIM card ,turn on airplane mode,reinsert it and turn off your phone(not reboot but power off).Wait for 1 minute and power it back on.Tada!Should be fixed!:fingers-crossed:
Thank you!
Thank you so much! I was worried I was going to have to try one of the more complicated fixes I've seen here. I was puzzled because after performing Joseph230's procedure to root and "convert" an S4 from AT&T to T-Mobile (http://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719) everything seemed fine and I reinstalled all my apps. Then, I get the "No SIM inserted" error out of nowhere!
After much researching I was losing hope of finding a fix guaranteed to work. Then I found your post and it worked like a charm! :highfive:
robermaldo
Thank You
Im so glad that this worked because I was losing hope that my imei or something was broken and I git scared then I found this and it actually worked I thought it was because 5.1.1 or something anyways thanks for the help I actually loged in my XDA account just to post that cause I just always use the browser
A coworker brought me his G2 that I have taken apart to fix many times before because it was having problems charging and turning on (black screen; rhythmic buzz from the vibration motor). I worked around that to get it booted temporarily but then the SIM connection seemed to suddenly fail. I replaced the motherboard entirely because some charge/power issues persisted and everything works perfectly EXCEPT that the replacement also doesn't see the SIM. Both are running stock LG Verizon Lollipop (assumed installed by OTA). No one was playing around with alternate ROMs or anything. None of the fixes in this thread help. The SIM slot is on the board so I hesitate to assume that the charge, mic, headphone flex PCB has something to do with it, but it is the only major common component (even replaced the screen again along with the battery, speaker, etc while leaving out useless components). Any suggestions?
Long version:
After a previous screen replacement it would only buzz when attempting to turn on or buzz repeatedly when attempting to charge until I loosened the black screw near the battery connector. I definitely narrowed it down to that particular screw, though I still couldn't say why (the previous tech who replaced the screen may have shorted the battery terminal near there). When he brought it back to me it was doing the same thing again even with the screw completely removed. Within minutes I had it booting just by poking around. Not sure what I did but I had to take it apart and poke around again to get it to come on after making the mistake of turning it off (went right back to buzzing). I'm pretty sure that the SIM card worked because he received a couple text messages when I first got it turned on (phone hadn't been booted in a day). After getting it to turn on I had to leave it on while reassembling, so I put the SIM tray back in when I was done. The owner was watching and asked why the status bar showed an "X" on the signal strength, so I told him that it was because you had to reboot after reinserting a SIM on most Android devices (as opposed to dual-SIM and iPhone devices). Though I couldn't turn off without causing the power problem, I could safely restart. Unfortunately, restarting only gave me the "Insert SIM" message at boot and nothing I could do would get it to see the inserted SIM. I tried many SIM cards but none worked. I replaced the motherboard expecting it to be a solution to both problems but only the power problems went away. The SIM card issue remained even though the SIM slot is built into the part I replaced and the part I purchased is supposed to be guaranteed, tested, clean IMEI, etc. I'm at a loss. I've taken out every unrelated component and replaced the screen again and replaced the battery so about the only thing that is common is the flex PCB with the mic, headphone jack, display connectors, etc running through it. Not sure how that could be a factor, but I'm replacing it too. In the mean time, does anyone have any suggestions for what could be wrong?
Update: A new mic/USB/headphone flex PCB fixed it. I'm not sure how that can cause the SIM card to not be detected, but I conclusively tested and that was definitely the problematic component: No SIM card detected on either motherboard with the old flex PCB, SIM card detected fine on both motherboards with the replacement flex PCB.

Hello, is your LG G2 still working with the new PCB flex?
Thanks a lot, this solution worked for me ?
i've done flash rom on Mtv Slash 3G 512 RAM Tablet, but no sim detected ....& i've followed your suggestion but no solution made...!!!
I had spent more than one month using CM13 based ROM thinking its ROM based issue. but this resolved the issue.
But now no sim issue has been resolved yet no mobile signals are working...
I have a vs980 or the Verizon lg g2. It bought it unlocked and I use T-Mobile. The data worked when I was on the stock os. I then got cm13 and everything worked good accept it wouldnt see my sim card or it would say no signal. And it had no info on the sim card in the about phone settings. So I tried a few other nightlys and nothing worked. I went down to cm12 and still I got the same error. I tried what you said here multiple times and it doesn't seem to help. Any help would be greatly appreciated. Thanks

I found a fix! Go into settings and select Mobile networks. When your in there there should be a "preferred network type" change that to global and there you go. Now I couldn't get that to work on cm13 because the settings would crash when you try to go into mobile networks. But I got it to work on cm12 just fine
dear sir. I have samsung galaxy grand duos i9082. i have installed custom rom 5.1.1 but after booting with new custom rom no sim card is coming. i have seen your valuable method and done as u said but it is not working on my phone. i have tried two to three time but no. i don't know how to fix it.

I have a galaxy note 3 -n900 I flashed CM13 after which my phone keeps saying SIM removed/inserted... And I can't remove my SIM without taking out my battery. Also my IEMI no. is correct. So no problem there
THANKS!!!
I've spent the last three weeks dealing with various radio bugs and issues, clearing preferences, wiping caches, factory resetting, and installing clean ROMs. All it took is to set the thing into airplane mode? You've got to be kidding me!
Thanks a lot for the solution hackarchive! :good::good::good:

sim no detection on leeco le2
Your solution not working on my leeco le2 . please suggested me another solution.
Need help with this one... I just bought the phone from someone on Facebook. Well phone is unlocked and when I put my att sim card in it says inserted sim and restarts but still says no sim when it restarts. I called Sony and they told me to hook it to computer and download the software again so I did and it still has the same problem. I put my wife sim card it it it will read that there's a sim card inserted but will never give me cell service. I don't know what else to do. Please if anyone knows what I could try please let me know.. Thanks

Check your mobile network - access point name....does it have any APN service option....
Yeah, do what Martin wrote, and also try yet another SIM card. If it detected your wife's SIM, then it's probably not a hardware issue. May I ask how old your SIM is?
The SIM tray on the Ultra is also one of the worst designed trays in the history of time, so be 100% sure that you've put it in correctly.
The sim is only maybe 6 months old.. I am going to go in the morning and see about another sim. Maybe it will work.

Okay, so it's definitely not the SIM card, but the phone did detect your wife's SIM, so I'm not sure what the issue could be

OK so I took the phone to my phone provider and got a new sim and it works great now. But when I make a call on it the screen goes black and can't turn it back on until the phone hangs up even if the phone is nowhere near my face. I have looked to maybe keeping the phone on during call but there is no setting for that. I have read a few forms about this and there's only stuff about screen protector or cases which I am not using either of them. Please if anyone know something about this please help.. Thanks
